To solve the inequality $\vert \frac {x+8}{3}\vert -3\gt 6$, we first isolate the absolute value expression by adding 3 to both sides of the inequality:<br /><br />$\vert \frac {x+8}{3}\vert \gt 9$<br /><br />Next, we split the inequality into two separate inequalities based on the definition of absolute value:<br /><br />$\frac {x+8}{3}\gt 9$ or $\frac {x+8}{3}\lt -9$<br /><br />Now, we solve each inequality separately:<br /><br />For $\frac {x+8}{3}\gt 9$, we multiply both sides by 3:<br /><br />$x+8\gt 27$<br /><br />Subtracting 8 from both sides gives:<br /><br />$x\gt 19$<br /><br />For $\frac {x+8}{3}\lt -9$, we multiply both sides by 3:<br /><br />$x+8\lt -27$<br /><br />Subtracting 8 from both sides gives:<br /><br />$x\lt -35$<br /><br />Therefore, the solution to the inequality is $x\lt -35$ or $x\gt 19$. The correct choice is A.
